Patent EP-0460447-A1 (EP)
Inventor: GISIN PAUL
IPC: A61B17/80
Filed: 1991-05-21
Abstract: The drill guide according to the invention is used for drilling bone-plate screw holes in bone fragments to be stabilised by means of a device which comprises a compression bone-plate with through-holes formed therein and matching spherical head screws. The drill guide has an inner hollow cylinder (3) which is intended for guiding the drill and which is axially displaceable in an outer hollow cylinder (4) by means of a spring mechanism (7,9,10), the plate-side end (2) of the outer hollow cylinder (4) and the projecting plate-side end (8) of the inner hollow cylinder (3) corresponding to the spherical shape of the underside of the head and of the shaft of the screws to be implanted. The main advantage of the drill guide according to the invention lies in the fact that those parts (2,8) of the drill guide coming into engagement with the plate hole match exactly the lower surface of the screw head and the external diameter of the screw thread. In this way, in contrast to drill guides according to the prior art, it is possible to obtain a geometrically accurate fit in any desired position. <IMAGE>

Abstract: A differential loading fluid check valve (50), including a unitized valve body (43) having a single service port (48) in its sidewall for selective access to the interior chamber (46) of the check valve. Check valve subassemblies (58,62) are installed and removed through the service port for valve assembly and service. The same valve body can be configured for either single or double check valve operation by adding or removing check valve subassemblies. Each check valve subassembly (58,62) includes a base with an aperture, a pivotally mounted clapper (21), and an overlying pivotally mounted cam arm (31), spring biased against the movable end of the clapper. An arcuate surface on the cam arm is engaged by the clapper as it moves from a closed position to an open position, providing a beneficial differential reduction in the pressure drop, or loading, through the check valve.

Abstract: A convenient method for the quantitative determination of a DNA polymerase includes contacting an aqueous test specimen suspected of containing the enzyme with the following : a single-stranded DNA template present in a concentration of at least 10- 8  molar bases, a DNA primer complementary to the template, a source of a metal polymerase cofactor, sufficient deoxyribonucleoside triphosphates to synthesize double-stranded DNA in the presence of the polymerase, and a colorimetric or fluorescent dye which is capable of providing a detectable signal when a primed single-stranded nucleic acid is converted to double-stranded DNA by the polymerase. The rate of signal generation is then measured and can be correlated with the level of DNA polymerase in the specimen using graphical or mathematical means. The results of this method are precise, having a covariance of less than 10%. A test kit includes the reagents needed for carrying out this method.

Date Jun. 27, 1991.A UHF carrier signal modulated by a video signal, where the frequency and the format of a line synchronization signal are known, is transmitted in a transmission region in a confined medium by a microwave link. In a reception region, two signals are received along two angularly offset privileged axes, each is frequency-demodulated along identical processing channels, the existence in the signal emitted from one of the channels, the "starting channel", of a periodic signal with the line synchronization frequency is checked and this signal is selected if the check proves positive. If the periodic signal disappears, the test is applied to the other channel; if that check is positive, this other channel is selected until this periodic signal disappears. Such a process is especially applicable in tunnels.

IPC: G05F1/56

Abstract: Dans des circuits intégrés ayant un amplificateur de signaux analogiques, par exemple dans des circuits de régulation, des déphasages se produisent à de hautes fréquences. Afin de supprimer les vibrations incontrôlées qui y sont associées, la réponse en amplitude et en phase est modifiée au moyen d'un condensateur de compensation de la réponse fréquentielle. La valeur de ce condensateur est proportionnelle à l'amplification. Les condensateurs intégrés occupent toutefois une grande surface sur la microplaquette. L'adjonction d'une valeur de commande non réglée (76) qui correspond approximativement à la valeur de seuil (79) permet de réduire l'amplification requise par l'amplificateur d'erreurs (71) du circuit de régulation. La contre-réaction peut ainsi être réduite, la valeur requise par le condensateur de compensation de la réponse fréquentielle, ainsi que la surface qu'il occupe sur la microplaquette, s'en trouvent diminuées. Ce circuit est utile pour des amplificateurs analogiques intégrés.

Abstract: L'invention se rapporte à un appareil de soutènement peu coûteux et facile à installer (14), qui sert à soutenir des assises de structure en sous-bassement, telle que des fondations (10) ou similaires, et qui utilise une ancre porteuse à vis hélicoïdale installée par une force hydraulique ou électrique (16), conjointement avec une unité de console d'assemblage (18) fixée à la fondation (10). L'ancre (16) est vissée dans la terre sous la fondation (10), plaçant ainsi l'extrémité droite de la tige (20) de l'ancre à proximité adjacente de la fondation (10). L'unité à console (18) comporte de préférence une plaque (28) contre laquelle vient s'appliquer la fondation et qui est pourvue d'une paire de parois espacées s'étendant vers l'extérieur (30, 32) fixées fermement à la plaque. Une console allongée en U (36) ainsi qu'un organe de retenue jointif (42) sont fixés amovibles aux parois (30, 32) et servent à retenir captives l'extrémité supérieure de la tige (20) de l'ancre, tandis que la console en U (36) comporte une paroi supérieure en forme de pièce transversale (38) dans laquelle est ménagée une ouverture taraudée (40). Un boulon de transmission de force fileté (54) vissé dans la pièce transversale (38) de la console vient se plaquer contre la butée terminale supérieure (22) de la tige (20) de l'ancre (16), de façon à ce que cette dernière serve de support porteur pour la fondation (10). Un couple de rotation est transmis à chaque ancre à vis pendant l'opération d'installation sous la forme d'une force indépendante d'un support correspondant et de la fondation, jusqu'à ce qu'une valeur de couple prédéterminée soit atteinte. Le couple de rotation s'appliquant sur l'ancre à vis est ensuite relâché et le poids mort ainsi que toute charge variable de la structure de la construction portée par l'unité à console sont transférés à l'ancre à vis.
